WIND MUSICAL INSTRUMENT.

Application filed Jul} 11 1917. Serial Ito-119,993.

To all Ii /win it may concern:

Be it known that l, Sua'x'ron a-c|tizcn ol Italy, and resident, of Newark,-

of musical notes upon the app ication of pressure.

The main Olljtct of my invention 15 to pro ride for nlltflll'lnllc\lllll'lllflll of the musical .sonnd produced by a bellows actuated reed,

,Iingstrolce of the bellows, effect the production of diflclcnt, musical functioning automatically, to uupartvariable movement to said valve in each air exelling stroke of thebellows.

Other features and advantages of my said invention will hereinafter appear.

Figure 1 is a plan view of my improved ap arutus.

"i 2 is a section on the line 1, null Fig. 3 is a partial sectional view showing the sound box and reed. In the example of my invention illustrated herewith, let 1 indicate the base, and 2 the upper member of a bellows,normally spread apart by a spring 3, and'who'se inclosure and hinge may he composed of paper or other flexible covering 4.

The. top 2 has an orifice '5 therethrough, and contiguous to said orifice is the vibratoryfend of a reed 6, which may lie upon the top 2, and cmiimunicate, at its free end, with a sound box 7, the latter also being mounted upon the top 2, near the forward end there of. A sheath 8, which may be of metal, ex-

2-2 of Fig.

. tends over the vibratory end of the reed, to

incloso the latterand said sheath, reed and sound box may all be firmly-secured upon the top 2, in air tight connection therewith, as by the embedding application of glue or other adhesive mutcrla he sound box 7 has on air exit orifice 9, controlled by a valve 10; and also an intake ol'ilico 11.

It. is through the variable operation of the valve 10, in the course of a single air expelthat I am able to arrangement also permit ting the the same to slip off the post face,

sounds from a single reed; The mechanism employed by me in accomplishing this purpose is as follows Secured ,lo the base 1, at its free end, is a post 12, which extends upu'ardlr. through a portion of the bright of the bellows, as expanded, said post having a curved terminal face li for a purpose to be described hereinafter.

lhe valve 10 is secured upon the sound box 7, at the rear of the orifice 9, and is of spring-like material, having a pad-like covering it to conlart with the box surface about orifice 9. Au upwardly extending fold in the material of valve 10, between its point. of corniection with the sound box and orifice 9, is provided to position the fulcrum of said valve near to orifice 9, which permits the soldcriug'of'thc valve to the sound box to bepcrforined at a more distant point, this valve 0pcrat-ion, in opening and closing, to be'pepformed a t. a more acute angle, and therefore more quickly responsive.

The valve 10 extends over the forward edge of top 2, and is bent. downwardly in the 'form of a tongue 15, with a curved terminal surface 16, which normally lies in.

cessirc notes of dlll'crcnt pitch, the return or expanding stroke of the bellows being ellected by the action of the spring 3.

This stated result is achieved by the tongue surface 16 meeting the face 13 of post, 12, when the members 1 and 2 are pressed. together-,the pressure thus applied to valve '10, causing it to yield at its fulcrum, and thus toopen orifice 9, emitting a note; continued closing'morement of the bellows then causing the tongue face outside so that the tension of the valve relaxes and: the valve becomes seatcd again to close orifice 9. Still however continuing the closing of the bellows, the tongue 15 will trorelfreely until its u per portion 17 meets the post 2. In a wind musical instrument comprisface 13 an then further inward movement ing a bellows having base and top portions of the ellows causes the post to again lift the combination with a sound box upon sai the valve for the emission of another note. top portion, an a reed therefor, said sound 30 5 us, in a complete inward stroke of the ox having an exit orifice, of a forwardly bellows, the valve is twice actuated by the opening spring valve for said orifice, a post 12. tongue extended downwardly from said I claim valve, said tongue having a curved terminal 1.
